ABS reset ?? CV boot replace??

[robgar]

My 2001 x5 4.4 (only 30,000 mi) needs the right front cv boot replaced, the axel is fine. I have been told by the dealer that only they can do this work as only they have a special tool for this job and that the ABS has to be reprogramed with their software or the brakes could suddenly lock up on the highway.
Is this in fact true? as a local shop that specilizes on foreign cars said that is not true they replace them all the time and they can do the work for half the price. I know them to be an honest business as they have worked on my families members cars for over 30 years. Thanks!!
